I'd take the opportunity to get a built shortblock. IAG has staged short blocks though I don't have any experience with them. I'd also consider replacing hard lines and make sure to follow the recommendations of removal of screen for AVCS and turbo. I'd also take the opportunity to replace the turbo as there was likely metal in the oil and the turbo probably won't be lasting long if it didn't go first.
